Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The above design can monitor the wind direction and wind force changes in the flight environment in real time by setting the wind force, wind direction and wind force sensor 13, the adjustment component 3, the drive component 4 and the wind resistance cover 5, and provide accurate data support for the flight control of the UAV. When encountering strong wind or sudden change of wind direction causing the UAV to shake and unable to hover stably, the balance rotor 31 in the adjustment component 3 can respond quickly, adjust its direction and wind force output according to the command of the UAV controller 12, and generate reverse wind force to offset the influence of external wind force, thereby effectively maintaining the balance state of the UAV and improving the flight stability. The flexible adjustment mechanism of the balance rotor 31 enables the UAV to quickly adjust its flight attitude when facing a complex and changeable flight environment, effectively cope with adverse conditions such as strong wind and side wind, and enhance the wind resistance and environmental adaptability of the UAV. The wind resistance cover 5 further reduces the direct impact of strong wind on the electric rotor 22, and effectively reduces the wind resistance by guiding the airflow to flow downward along the wing 2, thereby improving the flight efficiency and heading accuracy of the UAV.
[0023] Furthermore, a through groove 321 is provided on the upper end surface of the cross bar 32, and the front and rear arms of the through groove 321 are symmetrically provided with inwardly recessed grooves 322. A slider 311 is provided on the upper end surface of the balancing rotor 31, and the slider 311 is slidably connected in the through groove 321, and a driving member 33 is provided in the slider 311, and the driving member 33 is used to drive the slider 311 to slide in the through groove 321. When strong wind blows the drone, the driving member 33 is started to drive the slider 311 to move, so that the balancing rotor 31 is adjusted, and the balancing rotor 31 is moved left and right, and the downward pressure generated by the balancing rotors 31 at both ends is matched with the wind force according to the actual wind direction and wind force.
[0024] Furthermore, the upper and lower walls of the groove 322 are provided with staggered racks 323, the driving member 33 includes a dual-axis motor 331 and a first gear 332 meshing with the rack 323, the slider 311 is provided with a mounting chamber 313, the dual-axis motor 331 is installed in the mounting chamber 313, the output end of the dual-axis motor 331 passes through the mounting chamber 313 and extends into the groove 322, the first gear 332 is installed at the output end of the dual-axis motor 331 and meshes with the rack 323, and the upper end surface of the slider 311 is symmetrically provided with an integral The formed L-shaped plate 312, the slider 311 is slidably connected to the outer wall of the cross bar 32 through the L-shaped plate 312, and when in use, the first gear 332 is driven by the motor to rotate the first gear 332 in the rack 323. Since the rack 323 is staggered, when the first gear 332 rotates, it will drive the slider 311 to move, so that the balancing rotor 31 moves forward and backward. When moving, the L-shaped plate 312 is stuck on the outer wall of the cross bar 32, so that when the motor drives the first gear 332 to rotate, the slider 311 can move downward instead of rotating in place following the motor drive shaft.
[0025] Furthermore, the horizontal adjustment member 41 includes a sleeve 411, a connecting plate 412, a mounting column 413, a mounting cylinder 414 and a first motor 415. The first motor 415 is fixedly mounted on the bottom surface of the body 1, and the output shaft of the first motor 415 is arranged downwardly. The sleeve 411 is mounted on the bottom surface of the body 1 and covers the first motor 415. A bearing 418 is installed in the sleeve 411, and the mounting cylinder 414 is installed in the bearing 418. The connecting plate 412 is fixedly mounted on the outer wall of the mounting cylinder 414. The mounting column 413 is symmetrically mounted on the bottom surface of the connecting plate 412. A through hole 416 is provided on the left end surface of the mounting column 413. A rotating shaft 417 is rotatably connected in the through hole 416. The rotating shaft 417 is fixedly connected to the cross bar 32. The other end of the rotating shaft 417 is connected to the axial adjustment member 42, and the axial adjustment member 42 is mounted in the mounting cylinder 414. When in use, the first motor 415 is used to drive the sleeve 411 to rotate, so that the sleeve 411 drives the connecting plate 412 to rotate, the connecting plate 412 drives the mounting column 413 to rotate, and the mounting column 413 drives the cross bar 32 to rotate, so that the balancing rotor 31 can be rotated 360 degrees and adjusted, and can more flexibly generate reverse wind force to offset the influence of external wind force, thereby effectively maintaining the balance state of the drone.
[0026] Furthermore, the axial adjustment member 42 includes a mounting plate 421, a connecting member 422 and a second motor 423. The mounting plate 421 is mounted on the inner wall of the mounting tube 414. The connecting member 422 is arranged on the right end face of the mounting plate 421 and is respectively connected to the symmetrically arranged rotating shafts 417 for transmitting power to simultaneously rotate and adjust the left and right symmetrical cross bars 32. The second motor 423 is connected to the connecting member 422.
[0027] Furthermore, the connecting member 422 includes a mounting seat 424, a second gear 425, a third gear 426 and a connecting shaft 427. The mounting seat 424 is mounted on the right end surface of the mounting plate 421. The second gear 425 is connected to the mounting seat 424 for rotation symmetrically in front and back. The third gear 426 is connected to the mounting seat 424 for rotation symmetrically in left and right. The second gear 425 and the third gear 426 are meshed with each other. The connecting shaft 427 is respectively connected to the outer wall of the second gear 425. The rotating shaft 417 extends into the installation tube 414 and is rotatably connected to the connecting shaft 427. The second motor 423 is fixedly connected to one of the third gears 426. When in use, the third gear 426 is driven by the second motor 423, so that the second gear 425 is driven by the third gear 426. At this time, since the symmetrical second gears 425 are engaged with the third gear 426, when the third gear 426 rotates, the symmetrical second gears 425 rotate in opposite directions, so that the symmetrically arranged cross bars 32 can rotate in opposite directions respectively.
[0028] Furthermore, the wind resistance cover 5 includes a blocking cylinder 51 and a cylindrical fan blade 52, wherein a connecting plate 511 is symmetrically arranged in the blocking cylinder 51, and the connecting plate 511 is fixedly connected to the outer wall of the connecting rod 21, and the outer wall of the blocking cylinder 51 is provided with a plurality of wind guide grooves 512 that penetrate downwardly through the blocking cylinder 51, and the cylindrical fan blade 52 is rotatably connected to the outer wall of the blocking cylinder 51, and the cylindrical fan blade 52 includes a plurality of inclined blades 522 and a mounting ring 521 that is symmetrically arranged up and down, and the mounting ring 521 is rotatably connected to the outer wall of the blocking cylinder 51, and the blade 522 is mounted on the outer wall of the blocking cylinder 51, and the blade 522 is mounted on the outer wall of the blocking cylinder 51. The wind guide grooves 512 are spirally distributed on the outer wall of the blocking cylinder 51. The blocking cylinder 51, as the main windproof structure, can absorb and disperse part of the wind force, and the rotation of the cylindrical fan blades 52 can further guide the airflow, reduce the impact of wind resistance and turbulence on the UAV, thereby significantly improving the flight stability of the UAV. When in use, the wind blows toward the cylindrical fan blades 52, and through the combination of multiple inclined blades 522 and the mounting rings 521 symmetrically arranged up and down, a dynamic structure that can efficiently guide the airflow is formed, thereby effectively reducing wind resistance and enhancing the wind resistance of the UAV.
[0029] It should be noted that the inclination direction of the blade 522 and the spiral setting direction of the guide groove are the same as the rotation direction of the electric rotor 22, so that the derived wind can most effectively reduce wind resistance and enhance the wind resistance of the drone.
[0030] The working principle and use process of the present invention: When the drone takes off and heads, the wind force generated in the air is captured by the wind force, wind direction and wind force sensor 13. When the wind force is strong enough, the wind force, wind direction and wind force sensor 13 transmits a signal to the drone controller 12, so that the drone controller 12 starts the dual-axis motor 331, the first motor 415 and the second motor 423. After the dual-axis motor 331 is started, it drives the first gear 332 to move the slider 311 to adjust the horizontal position of the balancing rotor 31, so that the balancing rotor 31 can generate downward wind force, thereby balancing the body 1 and keeping the body 1 balanced against strong winds. At the same time, the first motor 415 starts to drive the mounting cylinder 414 to rotate, the mounting cylinder 414 drives the connecting disk 412 to rotate, the connecting disk 412 drives the mounting column 413 to rotate, and the mounting column 413 drives the cross bar 32 to rotate, so that the matching rotor rotates with the center point of the connecting disk 412 as the axis. After the second motor 423 is started, it drives the third gear 426 to rotate, and the third gear 426 drives the second gear 425 to rotate, so that the second gear 425 drives The connecting shaft 427 rotates, and the two connecting shafts 427 rotate in opposite directions. The connecting shaft 427 drives the cross bar 32 to rotate, so that the angle and position of the balancing rotor 31 can be flexibly adjusted according to the direction. At the same time, when strong wind contacts the blade 522, it can push the blade 522, so that the blade 522 drives the mounting ring 521 to rotate, forming a dynamic structure that can efficiently guide the airflow, and then enters the blocking cylinder 51, and is guided into the wind guide groove 512 through the blocking cylinder 51, and is spirally transported out of the blocking cylinder 51 through the wind guide groove 512, reducing the impact of wind resistance and turbulence on the drone, thereby significantly improving the flight stability of the drone, so that when encountering strong wind or sudden change in wind direction causing the drone to shake and unable to hover stably, its direction and wind output are adjusted according to the command of the drone controller 12, and reverse wind force is generated to offset the impact of external wind force, thereby effectively maintaining the balance state of the drone, and by guiding the airflow to flow downward along the wing 2, the wind resistance is effectively reduced, and the flight efficiency and heading accuracy of the drone are improved.
